TINTYP'E APPARATUS.

SPECIFICATION forming part of Letters Patent No. 638,907, dated December12, 1899.

Application filed April 5, 1899. Serial No. 711,868. (No model.)

To alt whom it may concern:

Be it known that we, WILLTAM A. OoPE, residing at Pratt, in the countyof Pratt, and JOHN L. MYERS, residing at Caldwell, in the county ofSummer, State of Kansas, citizens of the United States, have inventedcertain new and useful Improvements in Tintype Apparatus, of which thefollowing is a specification.

Our invention relates to tintype-machines, and has for its object toprovide an apparatus in which, after the plate-magazine has beensupplied and the developing and fixing baths filled, the plates aresupplied to the camera and passed through the baths by the m anipulationof devices outside the machine. This object we accomplish in the mannerand by the means hereinafter described in detail and particularlypointed out in the claims, reference being made to the accompanyingdrawings, in which like figures indicate like parts in all the views.

Figure 1 is a side elevation of our invention with case. Fig. 2 is aside elevation of same from right. Fig. 3 is a front view of same. Fig.4 is a central sectional view, partly in elevation. Fig. 5 is a detailview of top of bath-carriage. Fig. (3 is a detail view of magnets.

Our invention consists of two rectangular upright standards 1,preferably of sheet metal, with flanges projecting outward from thebottom and sides to give rigidity. The standards 1 may be braced by across-piece 2 between their lower ends. Secured between the upper endsof the standards 1 is a rectangular covered box 3. Arranged on thebottom of said box 8, in the forward part, is a plate-bed 4, open at therear. An inclined slide 5, having a longitudinal slot in its center, isplaced in said box 3 a little to the rear of the middle and secured tothe sides of said box 3, said slide having flanges extending forwardfrom its side and toward the lower end of said slide 5, bent inward toform a chute. A shaft 6 is journaled in the sides of said box 3 justback of said slide 5 and has one end formed into a crank outside saidbox 3. Mounted on said shaft 6 and normally extending through the slotin said slide 5 and over said plate-bed a is an arm 7. Two horseshoe-magnets 8 are arranged at a suitable distance apart and secured bya hinge 9 to the end of the arm 7, so that the open ends of said magnets8 rest in the plate-bed 4. Just in front of the foot of said slide 5 atthe mouth of the chute and through the bottom of said box 3 is atransverse slot 10. Opening into said box 3 at one side opposite saidplate-bed i is a projection 11, having its outer end normally closed bya swinging door 12 and secured to the same end one end ofa bag 13, theother end of which bag 13 is drawn together by a piece of elastic. Acamera 14,

of any of the usual forms, provided with aspringshutter 15, is securedbetween the standards 1 below said box 3, so that the plateholder 16will be just under the slot 10. A chute 17 extends from the top of thecamera 1th just over the plate-holder 16 to within a short distance ofthe slot 10. Just in front of said chute 17, above said camera 14,-, ashaft 18 is journaled in said standards 1, one end of said shaft 18being provided with a crank 19. Depending from said shaft 18 into saidcamera 14, one on each side said plate holder 16, are two wires 20, thelower ends of which wires 20 are bent at right angles and normallyextend under and form the bottom of said plate-holder 16. Extendingthrough the bottom of the camera 14, immediately under the plate-holder16, is a chute 21, the lower end of which rests normally on thebatlrcarriage 22. Secured to the side of the box 3 is a reservoir 23, inwhich the developing fluid is placed. A tube 24 connects the outlet ofsaid reservoir 23 with said chute 21. The bath-carriage 22 issemicylindrical, its ends being crescent-shaped and extending beyond thebody. At one side it is attached to ashaft 25, journaled in saidstandards -1 and provided at each end with a crank. From the bottom ofthe bath-carriage 22 a tube 26 extends to the receptacle 27. Normallythe bath-carriage 22 is held by the spring 28 against the bottom of thechute 21, which itcloses. Immediately under the bathcarriage 22 andsecured between the stand ards 1 is a chute 20, provided with a coupleof ribs 30 to keep the surface of the plate from contact with the wallof the chute 29 as it passes through. At the bottom of said chute 29, ina suitable receptacle, the fixingbath is placed. The crank at one end ofthe shaft 25 is connected to the lower end of a rod 31, which extends upabove the top of box 3, and the crank en the other end of the shaft 25is connected by a cam 32, working in a slide 33, attached to standards1, with the crank on the end of the shaft 6. The spring 3-1 returns theshaft 6 to its normal position. A lever 35 is mounted on a bracket 36,attached to the standards 1. The end of the long arm of said lever 35 isnormally drawn down by the spring 37. An arm 38 has its lower endattached to the long arm of said lever 35 intermediate its end andfulcrum by a pin passing through a slot in said lever 35. Said arm 38extends up aboveand is bent at right angles over the reservoir 23, itsend being connected with the upper end of a rod 39, which extends downthrough said reservoir and has on its lower end a stopper, closing theoutlet of said reservoir 23. The short arm of said lever 35 extends overand is adapted when pressed down -to engage and press down crank 19,which when released is returned to its normal position by a spring 10.Attached to the end of the short arm of said lever 35 is a rod ll, whichextends up above the box In the front of the camera let the usual lenses12 are placed, and in front of them extendsa hood 423, closed by thespring-shutter 15. Secured at its lower end to said springshutter 15 isa rod it, which extends above the box 3 The whole is secured by screwsthrough the flanges at the bottom of the standards 1 in a box 45, closedby a door 46 at one side and provided with an aperture 4:7 opposite theeye of the camera 1i and with holes 48, through which the upper ends ofthe rods 31, -'l1,and4c% extend. Registeringwiththemouth of the chute 29is a slot 4.) in the bottom of said box 45.

The operation of our invention is as follows: Sensitized plates arepassed through the bag 13 and projection 11 and placed face down in theplate-bed 4, the arm 7, carrying the magnets 8, being temporarily raisedout of the way. When a sufficient number of plates are in the bed a thearm 7 is allowed to resume its normal position, when the open ends ofthe magnets 8 will rest on the back of the topmost plate. New bypressing the rod down the shaft 25 is turned and the cam 32 is raised,carryingtheerank on the end of shaft 6, thereby turning the shaft 6 andraising the arm 7 and magnets S, which will attract and hold the topmostplate until it comes in contact with the slide 5, as the magnets 8 passthrough the slot in said slide 5, when it will be released. On beingreleased the plate will slide down through the slot 10 and chute 17 onthe plate-holder 10. A pressure downward on rod 4 L opens the shutter 15and exposes the plate. When the exposure has been sufficient, theshutter 15 springs bacl: into place, when the rod is released. Rod allis now used to press the short arm of the lever 35 down. This raises thearm 38, and rod 39 opens the outlet in the reservoir 23 and permits thedeveloping fluid to pass through the tube 24: to the chute 21, intowhich the plate has been dropped 3 Y the same movement, the short arm ofthe lever pressing down the crank 19, turning shaft 18, and throwingwires 20 forward, releasing the plate, which falls into chute 21. Whenthe plate has been sufficiently long in the developing fluid, rod 31 isagain pressed, bringing, as above explained, another plate before theeye of the camera 11 at the same time that it turns the bath-carriagedownward and drops the first plate through the chute 29 into areceptacle containing the fixingdaath. The developing ll uid drains intothe batlrcarriagc 22 and through the tube 20 into the receptacle 2.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
